[1] Her parents were the first whites to live with the newly discovered tribe of about 400 people, who hunted with bow and arrow, ate snakes, insects and worms, and practiced intertribal warfare and revenge killings.
Her best-selling first book Dschungelkind (Jungle Child) (Droemer Knaur, München 2005, ISBN 3-426-27361-6) describes her experiences in the two different cultures and her occasional nostalgia for the simpler, slower life of the tribe.
Her second book, Ruf des Dschungels (Call of the Jungle) (Droemer Knaur, München 2006, ISBN 3-426-27393-4) describes a visit to the Fayu that she undertook in late 2005.
A third book, "Jäger und Gejagte" (Hunter and prey) describes her experiences living in Europe.
The German group Gesellschaft für bedrohte Völker criticized her first book, claiming that it romanticized the life of the Fayu and pointing out that it failed to mention the human rights violations of the Indonesian government against West Papuan people, and their endangerment by clearing of the jungle and industrial projects.
